A 60-GHz CMOS sub-harmonic RF transceiver with an integrated on-chip artificial-magnetic-conductor (AMC) Yagi-antenna and a balun-bandpass-filter (BPF) fabricated in 90-nm technology is presented. With the AMC structure, the radiation efficiency and power gain of the on-chip antenna can be increased. The on-chip balun-BPF combines the integrated design of the balun and RF BPF to reduce the circuit...
Shifting spatial signal processing in multiantenna systems from the digital base band to the RF front-end allows the development of energy efficient (green) MIMO radios. An integrated transceiver using RF-MIMO is designed in 0.25 mum SiGe technology together with a four-element antenna array. Low correlation between the antennas was achieved by using different diversity techniques and by optimizing...
An ultra low power 400 MHz 128 kbps-FSK RF transceiver SoC which consumes less than 2 mA from a 1 V supply was implemented in a 0.18 mum CMOS technology for wireless medical applications and applied to a wireless hearing aid communication system, a new generation of hearing aid device. The transceiver was implemented fully differentially and directly matched to a non-50ohm miniaturized dipole antenna...
